Disclosure: I've practiced Bujinkan Ninjitsu 武神馆忍术 for 5 years now. I recommend, especially for the brainer types, a well rounded martial art like ninjitsu, aikido, gong fu, qigong. Something like Boxing or BJJ will give you the physical fitness that you can get from most forms of exercise, but they lack the mental and spiritual refinement that comes from practice of a "true" martial art. The emphasis on art there implies that it is a true art form, taking years of discipline and practice to grasp just the basics. Ninjitsu is deadly efficient in combat, combines spiritual refinement (meditation, mindfulness, discipline), survival techniques (herbalism, meteorology, etc.), combat techniques and strategy into a complete package. http://en.wikipedia.org/wiki/Ninjutsu http://en.wikipedia.org/wiki/Ninjutsu
